If you've already drawn it in SketchUp, you have created a model. You can save it and copy the SKP file to a USB stick to transport it to his computer or you can probably just e-mail the file as long as it isn't larger than your e-mail service will allow.
As for letting him orbit, zoom and so on, he can install SketchUp and then open the file. Or, there's the SketchUp Viewer available for download here for PC and Mac and the Mobile Viewer which would let him look at it on an iOS or Android device.
If you give him the SKP file, there's nothing to stop him installing SketchUp and then modifying the file.
What is the ultimate use for the plan you've created?
